2 Claims. (63.120-49) This invention relates broadly to fountain pensand analogous writing implements, and more particularly to an attachmenttherefor in the form of an ink scraper or eraser.

In accordance with the present invention an ink eraser formed of metalor other suitable analogous material is provided for attachment to afountain pen and is so equipped as to cooperate with the usual clip withwhich fountain pens are generally equipped, in a manner to presentrotation of the eraser attachment about the fountain pen as an axiswhenthe attachment is in a position for and is being used in erasing anymark which the operator may wish to eradicate. g

The invention together with its objects and advantages will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawing, wherein:

Figure 1 is an elevational view of a fountain pen having the attachmentapplied thereto.

Figure 2 is an elevational view taken at right angles to Figure 1.

Figure 3 is a view similar to Figure 2 but showing the eraser in aposition for use on the fountain pen.

Figure 4 is a blankfroin formed, and

Figure 5 is a sectional view taken substantially on the line 5-5 ofFigure 2.

which the eraser is Referring to the drawing by reference numerals I itwill be seen that the eraser indicated generally by the referencenumeral 5, in the preferred embodiment thereof is cut from a singleblank of suitable material, preferably metal, cut, shaped anddimensioned to provide a relatively narrow plate 6 having one end offsetthereto to provide a scraper or blade 1 equipped at its terminal edgewith a knife edge as clearly suggested in the drawin Adi acent the endthereof remote from the blade part I plate t-is provided with a pair ofoppositely extending lateral projections or spring fingers t and adaptedto engage the cap 9 of a fountain pen i in a manner clearly shown in thedrawing for retaining the device on the cap for sliding movement alongthe cap 9, g

As clearly shown in the drawing when the hugers t are bent intoembracing position about the cap t the space between the terminals ofthe fingers t is suflicient to accommodate the anchored end of the usualclip I I with which the fountain pen cap 3 is equipped in a conventionalmanner,

Normally the device 5 is positioned on the cap as shown in Figures 1 and2. When, however. it s is desired to use the blade I for eradicating amark the device 5 is slid from the position shown in Figures 1 and 2 tothe position shown in Figure 3 and when in this position it will be seenthat the blade 1 projects beyond the end of the cap it t to be used forscraping or erasing any mark the operator may wish to eradicate. when inthis position the anchored end of the clip i l isaccommodated'betweenthe meeting ends of the spring fingers t and thus acts as a stop against16 which the free ends of the-fingers abut to effectively prevent arotation of the scraper about the cap 9 as an axis. Thus the member 8will be positively and eflectively held in position for use duringactual use of the scraper or eraser.

Having thus described the invention what is claimed as new is:

i. The combination with a fountain pen cap having a retaining clipanchored at one end thereto, of an eraser consisting of a plateformed atone end to provide a scraping element, and provided at the end remotefrom the scraping element with retaining fingers extending laterallyfrom opposite edges thereof and curved to fit about and embrace the capwith the free com 30 fronting ends of the fingers spaced apart adistance sumcient to receive therebetween the fixed end of said clip forengagement with said end of the clip to prevent rotation of the eraserabout the cap as an axis. a 35 2. An attachment for pens comprising acap having a pocket engaging clasp secured at one end to the cap at oneside of the cap and a scraper blade disposed at the side of the capdiametrically opposite to the engaging clasp, and provided withoppositedly extending curved spring fingers em= bracing the cap forslidably retaining the scraper element thereon, said fingers having freeends terminating in spaced relation to accommodate therebetween thefixed ends of the pocket engaging clasp and adapted to be arranged toengage said end of the clasp when an end of the eraser member isprojected beyond one end of said cap. and for the purpose specified.
